Radar imaging mechanism of the Birkenfels wreck in the southern North Sea [PDF]
, 2010 Varying tidal currents close to the sea bed cause sediment motion around wrecks leading to formation of scour holes and sand ribbons. Consequently, scouring destabilizes the position and shape of wrecks. Changing water depths above the shallowest parts

The influence of velocity variability on the determination of wind profiles [PDF]
, 1986 High sensitivity radars allow the determination of velocity estimates at time resolutions down to one minute or better. Because of the variability introduced to the mean wind due to turbulence and waves, the high resolution profiles may not be too useful

AS‐pHopt: An Optimal pH Prediction Model Enhanced by Active Site of Enzymes
Advanced Intelligent Discovery, EarlyView.To address the low accuracy of enzyme optimal pH (pHopt) prediction, this study develops active site‐based pHopt (AS‐pHopt), a prediction model enhanced by active site information and pseudo‐label prediction. Integrating key structural and physicochemical features affecting enzyme pHopt, AS‐pHopt uses Evolutionary Scale Modeling (ESM)‐2 with active ...
